Our Window Services in Stamford, CT
Energy-Efficient Windows
Stamford runs a long heating season and a short cooling one. That single fact decides most of what belongs in a window here, and it points in the opposite direction from the glass packages written for Sun Belt catalogs.
Vinyl Windows
Vinyl is the right answer for a great many Stamford houses, and we are happy to say so. On a Springdale cape or a Belltown ranch with ordinary openings, a welded vinyl window is durable, warm at the frame and a fraction of the cost of anything else.
Fiberglass Windows
Fiberglass earns its price in one situation this city produces often: a large opening, a dark exterior color, and thirty years of not wanting to revisit the decision. That is a narrow case, and it is a real one.
Wood and Clad-Wood Windows
Most of Stamford's pre-war houses were built with wood sash, and a good number of them still have it. Before we quote a replacement we look at whether the original is worth keeping, because in this stock it very often is.
Thermally Broken Aluminum Windows
Plain aluminum windows have no business in a Connecticut house, and we will not sell them for one. Aluminum conducts heat hundreds of times better than vinyl or wood, so an untreated frame becomes the coldest surface in the room and runs with condensation on a 7-degree January morning.
Double-Hung Windows
The double-hung is the default window of this city's older stock, and Stamford's version of it is tall. A 1920s opening carrying a sash close to three feet wide and over three feet high is common, and that sash is heavy long before anyone chooses a glass package.
Casement and Awning Windows
Casements seal better than anything else on the market. Cranking the sash shut draws it down onto a gasket that compresses around the full perimeter, which is why these units post the lowest air-leakage figures in most manufacturers' catalogs.
Horizontal Sliding Windows
A horizontal slider is the right window for a wide, short opening, and Stamford's postwar ranches and split-levels are full of them. Where an opening is wider than it is tall, a slider fills it cleanly and every other operating type looks wrong and works worse.
Bay and Bow Windows
A bay or bow does three jobs at once: it glazes an opening, it carries load, and it wears a small roof. In this climate the roof is what decides whether the thing lasts, and it is the part most quotes say nothing about.
Picture and Architectural Glass
Every other page here eventually points back to this one. Fixed architectural glass is the point at which a window stops being a catalog item and turns into an engineering problem, and this market orders a great deal of it.
Egress Windows
Most pages about escape windows are arithmetic. Ours is not, because Connecticut wrote two provisions that change the answer here, and neither one is in the national conversation about net clear openings.
Impact and Hurricane Windows
We sell laminated glass and we install it often. We will not sell it to you on the grounds that Connecticut requires it, because at ordinary risk categories this state does not, and the table that says so is a matter of public record.
Patio Sliding Doors
A patio door is the heaviest moving thing in a house and the one most exposed to weather. In this climate it also has to survive snow sitting against its sill for days, which is why the details that matter here are not the ones featured in the showroom.
French Doors
French doors suit this housing stock better than sliders do. On a pre-war colonial or a shingled house with divided-light sash, a pair of hinged doors matches the elevation in a way a horizontal slider never will, and they open the wall completely.
Entry Doors
An entry door is judged from the street and felt in the hallway, and in a market where the front elevation matters it is one of the few purchases doing both jobs at once. It is also where the sidelites, not the door, lose most of the heat.
Window Screens
Screens are the smallest thing on this site and the most common reason people call in May. They are also a job we are happy to do on its own, without any conversation about replacing the windows behind them.
Glass Repair and Sealed Unit Replacement
A failed sealed unit is not a failed window. If the frame is square, the hardware runs and the sash is sound, replacing the glass alone runs a fraction of a whole unit, and in an oversized opening it is often the only quick answer.
Commercial Storefront Glass
Stamford has a downtown office core, a retail spine along Bedford and Summer Streets, and a large stock of one and two-story commercial buildings across Glenbrook, Springdale and the South End. Those buildings use storefront systems, and storefront is a different animal from residential window work.

Energy-Efficient Windows
Stamford runs a long heating season and a short cooling one. That single fact decides most of what belongs in a window here, and it points in the opposite direction from the glass packages written for Sun Belt catalogs. The prescriptive number for this climate zone is a whole-unit U-factor of 0.30, and the mandatory limit is easy to hit.

Vinyl Windows
Vinyl is the right answer for a great many Stamford houses, and we are happy to say so. On a Springdale cape or a Belltown ranch with ordinary openings, a welded vinyl window is durable, warm at the frame and a fraction of the cost of anything else. The material has a ceiling, though, and the ceiling is a size rather than a price.

Fiberglass Windows

Wood and Clad-Wood Windows
Most of Stamford's pre-war houses were built with wood sash, and a good number of them still have it. Before we quote a replacement we look at whether the original is worth keeping, because in this stock it very often is. Old-growth sash is denser and more rot-resistant than anything milled today, and a putty-glazed pane in a straight frame can be reglazed, re-roped and weatherstripped for a fraction of a new unit.

Thermally Broken Aluminum Windows
Plain aluminum windows have no business in a Connecticut house, and we will not sell them for one. Aluminum conducts heat hundreds of times better than vinyl or wood, so an untreated frame becomes the coldest surface in the room and runs with condensation on a 7-degree January morning. That is the reflex answer, and it is right for the old single-glazed aluminum still found in 1960s additions around town.

Double-Hung Windows
The double-hung is the default window of this city's older stock, and Stamford's version of it is tall. A 1920s opening carrying a sash close to three feet wide and over three feet high is common, and that sash is heavy long before anyone chooses a glass package. Weight is the whole story on this page.

Casement and Awning Windows
Casements seal better than anything else on the market. Cranking the sash shut draws it down onto a gasket that compresses around the full perimeter, which is why these units post the lowest air-leakage figures in most manufacturers' catalogs. In a heating climate that matters more than it sounds.

Horizontal Sliding Windows
A horizontal slider is the right window for a wide, short opening, and Stamford's postwar ranches and split-levels are full of them. Where an opening is wider than it is tall, a slider fills it cleanly and every other operating type looks wrong and works worse. The trade is sealing.

Bay and Bow Windows
A bay or bow does three jobs at once: it glazes an opening, it carries load, and it wears a small roof. In this climate the roof is what decides whether the thing lasts, and it is the part most quotes say nothing about. A bay projects from the wall, so it carries a small roof, and in Fairfield County that roof carries snow.

Impact and Hurricane Windows
We sell laminated glass and we install it often. We will not sell it to you on the grounds that Connecticut requires it, because at ordinary risk categories this state does not, and the table that says so is a matter of public record.

French Doors
French doors suit this housing stock better than sliders do. On a pre-war colonial or a shingled house with divided-light sash, a pair of hinged doors matches the elevation in a way a horizontal slider never will, and they open the wall completely. The engineering problem is sag.

Window Screens
Screens are the smallest thing on this site and the most common reason people call in May. They are also a job we are happy to do on its own, without any conversation about replacing the windows behind them. Rescreening an existing frame is straightforward and cheap when the frame is straight: the old mesh comes out, the spline channel is cleaned, new mesh goes in under even tension and the spline is rolled home.

Glass Repair and Sealed Unit Replacement
A failed sealed unit is not a failed window. If the frame is square, the hardware runs and the sash is sound, replacing the glass alone runs a fraction of a whole unit, and in an oversized opening it is often the only quick answer. Fogging between the panes is a seal failure.

Commercial Storefront Glass
Stamford has a downtown office core, a retail spine along Bedford and Summer Streets, and a large stock of one and two-story commercial buildings across Glenbrook, Springdale and the South End. Those buildings use storefront systems, and storefront is a different animal from residential window work.
A storefront system is a framed grid of aluminum, typically a four-and-a-half-inch or six-inch deep section, glazed in the field with gaskets or wet sealant and installed as a non-load-bearing infill between floor slabs or in a masonry opening.

What Stamford property owners ask us
Which window services does Stamford Window Replacement handle?
Everything listed on this page, residential and commercial, across Stamford and southwestern Fairfield County. Work is done by our own crews rather than handed to whoever is cheapest that week, which is the only way the workmanship warranty means anything.
Can I combine more than one service in a single job?
Yes, and it is usually cheaper. Bundling window work into one mobilization saves setup, disposal and travel, and it means one crew, one schedule and one written free estimate instead of three contractors blaming each other.
Do you give free estimates for every service?
Every one. We come out, measure, look at the real condition of the work area, and put an itemized free estimate in writing with materials and scope spelled out. No charge, no deposit, and no obligation to book.
What Stamford Customers Say
They talked us out of half the order. Two of the sash we wanted replaced only needed balances and weatherstrip, and they said so before quoting. The four that did get replaced came with a schedule showing the weight and glass package for each one, and the crew set them in a day.
Our wide picture window cracked from the edge inward and two companies quoted a full replacement. This crew explained it was thermal stress, remade the lite in heat-strengthened glass at a quarter of the price, and it went into the existing sash in under an hour. It has been through two summers since.
The rear wall of our addition was one enormous fixed unit and nobody would touch it. They split it into three with a mullion between, planned the lift before ordering, and the whole thing was in by mid afternoon. The estimate had the access cost on it from the beginning, which we appreciated.
We were told by another contractor that our bedroom windows would need the openings cut larger for escape requirements. These folks quoted the code section that exempts replacements, fitted the largest standard size that fit, and added opening control devices upstairs. Straightforward, and it saved us the framing work entirely.
